I don't think you'd beat low stakes live using Miller's frequencies even if you
did look at your hand.
Those games are full of multiway pots with stations aren't they? C-betting 70%+ and barreling turn and river at the same high frequencies would likely mean you end up value-owning yourself, and your bluffs wouldn't work very often.
I've seen someone play (and beat) 2NL zoom without looking at their cards. They played 'exploitatively', and only opened on the BTN or SB if everyone else folded. They did not call or 3-bet pre at all, since their entire strategy was based on stealing pre, or taking down the pot with a c-bet.
EDIT: I also vaguely remember a PLO endboss doing a propbet where he actually beat PLO50 zoom without looking at his cards. That just blows my mind, because card removal is so important in PLO. Or at least I thought it was. I guess if you understand how ranges hit each board, and your opponents are predictable, then your own cards don't matter quite so much.
